  1. So im on day 40 of veg and 2 of my plants are showing similar symptoms, ones a little worse right now the other seems to be just starting whatever is going on. The first one is og fem clone I had got from a buddy. It did have spider mites so i sprayed with doktor doom and havent seen any signs of them. I trimmed alot off him and hes been recovering well until over night he kinda did a 360. The other is greencrack fem. There in a 4x4 tent under 315cmh. Temps avg around 26-27c 20-21c at night rh 35-40%. Growing in coco with canna nutes I always ph everything staggering between 5.8-6.2. Do i just need to feed them more? Right now im feeding about 1.2 ec or 590ppm (500). Any help is much appreciated.

  4. Seems to be really effecting the new growth. I brought them outside for a min so it was more natural light.

  5. So you sprayed yesterday and today they look like that? Or did you spray a few days ago and defoliate yesterday ? When you sprayed where your lights on ? What are your light to plant distances ?

  6. I defoliated right before i sprayed to try and get the worst parts off before hand. Gave them a light spray at night. The next morning i checked them before lights came on and they were dry. After the first day they had a slight burn on the newer leaves but thats about it. Light is about 22 inches away from canopy.

  7. I think its safe to say they didn't like the spray and probably a little shocked. Give it a few days with your same routine (except the bug spray lol) and see what happens. looks almost like a burn.
     
  8. You have a Sulfur Deficiency mate:)

  9. Where the leaves already showing those colors before you sprayed? Sulfur deficiencies don't happen overnight. Digga could very well be right.

  10. It started maybe a week and a cpl days ago I noticed the leaves were becoming a pale green, but nothing that yellow. I thought it might be nitrogen def starting but i didnt know sulfur def can cause leaf tips to curl downward too. What would you suggest to aid the sulfur def?
